| UNIT SPECIFIC OBJECTIVES CONTENT TEACHING AND LEARNING ACTIVITIES EVALUATION UNIT 6 SHEARING FORCES AND BENDING MOMENT DIAGRAMS UNIT 7 CENTRE OF GRAVITY OF FORCES ACTING ON A BODY The student will be able to 4.6.1 explain shearing and forces and bending moments their effects on abeam describe the variation of shearing forces and bending moments along the length of abeam construct shearing force and bending moment diagrams graphically. 4.7.1 explain the term centre of gravity. 4.7.2 determine the centre of gravity of forces. Shearing forces and bending moments. Effects of shearing forces and bending moments. Variations of shearing forces and bending moments along the length of abeam. Shearing force and bending moment diagrams for 3. concentrated and uniformly distributed loads. 4. simply supported beams and cantilevers. Centre of gravity of forces. Centre of gravity of forces acting on a section (e.g. lamina of geometrical shapes. Assist students to discuss shearing forces and bending moments. Using charts, group students to discuss effects of shearing forces and bending moments. Using charts, show the shearing force and bending moment diagrams for concentrated and evenly distributed loads. Guide students to solve simple problems on shearing force and bending moments graphically. Demonstrate graphically the construction of shearing force and bending moment diagrams for simply supported beam and cantilever with concentrated and uniformly distributed loads. With the aid of sketches and charts, group students to discuss centre of gravity. Illustrate how to determine the centre of gravity of simple geometrical shapes. Guide students to determine positions of centroid of different sections graphically. Illustrate the construction for the determination of centre of gravity by 3. finding the resultant of all vertical forces 4. finding the resultant of all horizontal forces Students to explain the effects of shearing forces and bending moments in a beam.
